\section{Conclusion}
\label{sec:conclusion}
We reported on the run of the OSQAR experiment in the year 2014. In total, we recorded 178\,h of data, of which nearly $80\%$ was used for the subsequent data analysis aiming at the search for scalar- and pseudo-scalar axion-like particles. In contrast to the previous years, the experiment was performed with an improved laser- and photon detection system, as well as an improved analysis strategy. Since no excess above the background-only hypotheses has been observed, 95\% confidence limits have been derived. The derived limits exclude a di-photon coupling strength of $3.2 \cdot 10^{-8} \GeV^{-1}$ and $3.5 \cdot 10^{-8} \GeV^{-1}$ for scalar- and pseudo-scalar axion-like particles in the massless limit. These results are so far the most stringest constraints on axion like particles in LSW-type experiments.
